I sell Ac Delco batteries at my shop and have never any issues with them. I had one go bad in one of my customers cars in the last 5 years and there was no hassle for a free replacement. We also have cold winters here. Just be carefull if you do purchase an ac delco because they have a professional series battery and a 2nd line which you would find at Walmart. Be sure you get the professional series. Maybe you could find a motorcraft cover for it
